The tilt of Earth’s axis.
Earth’s axis is tilted about 23.5°, so as Earth orbits the Sun different hemispheres are tilted toward or away from the Sun. That changes the Sun’s angle and the length of daylight, producing the seasons. The orbit’s shape or the Earth–Sun distance have only very small effects on seasons; the orbit’s direction doesn’t cause them.
